Encinitas homes from Cardiff to Olivenhain can move to a tankless water heater, and with a median build year of 1980 many of them need a new vent and a larger gas line to do it. SDG&E supplies the gas here. Call the number on this page to be connected with a local plumber in Encinitas.
Tankless in Encinitas
Encinitas is a group of communities: Cardiff, Old Encinitas, Leucadia, New Encinitas and Olivenhain. San Dieguito Water District serves Cardiff, Old Encinitas, Leucadia and part of New Encinitas, while Olivenhain Municipal Water District covers other parts of the city; the City's MyEncinitas Map shows which applies to your address. Each district publishes its own annual report, which is where to look up mineral content before deciding how to protect a tankless heat exchanger. Close to the beach, salt air favors an indoor location or a well-sheltered outdoor one.
Census survey figures put the median Encinitas home at 1980. Houses from that period often have a tank heater tucked in a garage corner or closet, vented through a flue it shares with the furnace. A gas tankless unit needs its own sealed vent, and the original gas pipe was rarely sized for the much larger burner, so both get checked before a model is chosen.
What to do now
- Check the current heater. If a tank is leaking, close its cold supply valve and set the gas control to off or pilot before planning anything else.
- Find your water district on the MyEncinitas Map and open its water quality report.
- Count the fixtures that run together during your busiest hour, since that number drives unit size.
- Look at where a new vent could exit and how far the heater sits from the gas meter.
- Plan on a permit through the City's Development Services building group.
- If you notice any gas smell, stop there: leave the house, then call 911 and SDG&E at 1-800-611-7343.
Symptoms on an existing tankless unit
| Symptom | Likely cause |
|---|---|
| Hot water fades at high flow | Scale on the heat exchanger or a unit too small for the load |
| Short cold slug between hot draws | Normal restart lag, worse with repeated short draws |
| Unit won't fire at a trickle | Flow below the activation minimum or a clogged inlet screen |
| Ignition or flame fault codes | Undersized gas supply, blocked vent or a worn igniter |
| Water pooling under the unit | Condensate line trouble or a loose fitting |
Cost factors
- Gas line sizing from the meter to the heater
- Vent route and the wall or roof penetration
- Condensing versus non-condensing unit
- Isolation valves and any scale treatment
- Permit and inspection
- Taking out the old tank
